Zulip founder Tim Abbott announced a major transition for the open-source team chat platform, donating the company to a newly created Zulip Foundation. Abbott and three senior team members are stepping back to join Anthropic, while the independent nonprofit will steward the project with a renewed commitment to its values. This move ensures long-term stability for the platform used by thousands of companies and research communities.

The Zulip Foundation will oversee development of the platform known for its unique topic-based threading model, which allows parallel conversations without chaos. April's Zulip 12.0 release incorporated 5,500 commits from 160 contributors worldwide. The foundation's board includes Abbott and others who have led Zulip for years, plus experts from various fields, with Kim Vandiver joining as Interim President to ensure smooth operations.

The new governance structure formalizes Zulip's commitment to public-interest organizations and creates new funding opportunities. As a nonprofit, Zulip can now apply for grants and accept tax-deductible donations, previously unavailable. This allows the foundation to maintain its values-focused approach without commercial pressure, ensuring the platform remains dedicated to community needs rather than shareholder interests. The transition represents a significant shift in how open-source projects can be sustainably funded and governed.
